A repairing method of a liquid crystal display panel having a gravity defect includes steps of providing a first pressure to the liquid crystal display panel. Next, a second pressure is continuously provided to the liquid crystal display panel, and a section from the edge of the liquid crystal panel to the sealant is removed and forming an opening through the closed sealant frame. Then, forcing out the excess liquid crystal to flow out the panel through the cut off sections, cleaning out the excess material including LC mixture around the opening, and sealing the opening with a fresh end sealant. After that, providing a third pressure to the liquid crystal display panel, curing the end sealant to seal the opening, and then removing the third pressure. Finally, annealing the liquid crystal display panel to recover original display quality.
A repairing method for a liquid crystal display panel having a pair of substrates, a closed sealant frame, and liquid crystal filled between the substrates and encapsulated by the closed sealant frame, comprising steps of:
